EXTENSION-TABLE.

Specification of Application led March 8,

esmas.

To all whom it may concern:

Be it known that I, Emir. Troiani, a citizen of the United States, residi'ng at Hastings, in the county of Barry and State of lVIichioan, have invented new 'and useful Improvements in Extension-Tables, of which the followingis a specification, reference being had to the drawings forming a part thereof.

' The purpose of this invention is to provide an improved means for controlling the extension ot' a table of the type in which the top is extensible independently of the 'extension ot' the pedestal, in such manner as to 'prevent Iunequal extension when fillers in.

tei-posed occupy the. space between the sepaated table members.

It consists of the features of construction shown and described as indicated in the claims.

In the drawings Figure 1 is a top plan of a table equipped with this invention having the top members partly broken away to disclose the operatingdevices. lig. 2 is a section at the line 2.--2 on llig. 1. Fig. 3 is a view similar to Fig. 1 showing the table members partly extended for the admission. ot' one filler. Fig. elv is a detail plan view ot' the escapement slide. llig. 5 is a side elevation ot the same. Fig. (i is a top .plan view and liig. T is a `side elevation ot' one ot the stop dogs. Fig. S is a` top plan view and lfig. 9 is a side elevation ot' the other dog.

'.l`he drawings represent a table having a pedestal which is extensible', and also having table members extensible on the respective pedestal members. The two pedestal members, 1, 1, are connected by slides, 4 and 5, attached to the respective pedestal members for sliding` upon each other in the cuslom'ary manner. The table top members, 2 and 3, are provided with slides, (i and 7, attached tothem respectivel'yhavlng sliding' engagement respectively with the pedestal slides, 4 and 5, of the corresponding pedestal members. This construction, e.\:cepty as to one feature hereinafter pointed out, will be recognized as the customary one for eX-tension of tables of this type, in which the top' is .extensible independently of-the pedestal, and also with the pedestal when the' latter is extended. The specific purpose of the invention,

which is to prevent. the table top members,

ywhen extended forthe admission of lillers,

unequally at the opposite ends, is effectedby the devices and features of construction which will now be described. 'F or the purpose of utilizingthe slides in the control of the extension ot' the table top members for the purpose indicated and utilizing the questionit is desirable to have the two innermost slides pertain and be attached to the two opposite tabl-e top members, so that the engagement of these slides lshall constitute engagement of said members respectively. rlhis involves la change from the usual construction and arrangement of eX- -tension slides, the customary construction 'being that the two sets of slides arev symmetrically disposed and arranged so that the two innermost slides pertain to .one table top member and the two outermost slides to the other top member, the pedestal slides next to said table top slides respectively pertaining to the corresponding pedestal members.

In the structune shown, the two innermost slides, 6 and 7, pertain to the opposite table top members, 2 and 3,respectively, the slide, t, next to the inner slide, 6, pertaining to the pedestal. member, 1, on which the table top member, 2, is mounted, and the slide, 5, next to the innermost slide, 7, pertaining to the pedestal. member, la, upon which the top member, 3, is mounted, the slides, 4 and 5, being attached to the same pedestal innembers as the slides, t and 5, respectively and the slides, Gland 7, being attached to the same table members as the slides, 6 and 7 respectively. Upon the bridge or pedestal cap 8, pertaining to one pedestal member (it is immaterial which one) there is mounted for sliding, a plate, 9, which is secured and guided in its sliding movement by bolts, 10, 10, engaging in slots, 9a, 9a, in the plate. At diagonally opposite corners of the plate it the slides 6 and 7 respectively, there arel pivoted dogs, 11, and 11, oit-set from the slides respectively such distances that at one limit ofthe sliding movement of the plate 9, the dogs can pass by one end of the lips, 9b when the table top members are drawn apart. Other dogs, 12, 12a, are also mountsame .pivots with the dogs, 11 and 11, respectively, and each spaced from them by an interval substantially equal to its own thickness. All the dogs, 11, 11a and 12, 12a,

have abrupt shoulders or heads facing the space between the slides for the devices inis provided with upstanding lips, 9b.' On

ed on these slides, most conveniently on the lips, 9b, 9,"respectively. The heads 12b of the dogs, 12; and 12, when the table top members .are closed together stand at a distance from the lips, 9?, 9b, respectively, equal to' substantially one-haltet' a iller Width, so that upon the'table top members being extended until the heads of'said dogs collide with thelips, 9", the intervalbetween the table top members is suficient to admit one" filler, and no further extension of the table top can be madel until'movement of the plate, 9, (to the left in Fig. 1), removes r the ips 9b from the paths of the shoulders 12b ofthe dogs so that lthe dogs can pass 15 across the late 9; andsuch movement of i one only o them resultin from extending only one tablev top inem er another halt filler Width, cannot exceed that amount,`be

. cause the shoulders 11b of the dogs 1 1` and 20 11a vdistant from the shoulders 12b of the doUs 12 and 12 by a half filler Width, Will collide With the lip 9b which in moving out of the paths of the shoulders 12b moves into the paths of the shoulders 11". llt is there- `fore necessary in order to get spacefor the second iiller to moveboth top members as last indicated so that the dogs carried by both stand in the same relation to the respective lips 9b on the plate 9. Theplate, 9,.being now thrust in the opposite direction. to the opposite limit of its sliding movement, the path of the shoulders 11b of the second dogs,

. 11 and 11, is cleared, vand the slides to which they,Y are respectively attached, and thetable top members carried thereby, may be moved for extension another half'filler Width eachil4 By such alternation of action, each. table top member being moved a half iller width t'ro'ni ccntratposition, and that to admit 4o rst one filler and nexttivo fillers, the table top is kept in balanced relation tothe pedestal. The slides are usually constructed-A and may be so understoodr in lthis case-for extension only to the extent of three liners, 45,and after extension for the twoiillers is made, unequal extension :tor the third filler is obviously impossible, and no precaution -is necessary in respect thereto except the customary limitation of the slides. When .greater extension is desired than that which can be obtained by extending the table top inembers'upon the pedestal mem- `Y bers 1n the manner above described, the ex` tension of the table top members'will be first made. to theilimit of three fillers, and the lpedestalvwill then be extended in the usual 'manner'. ln the latter extension, it Wil be observedv that the devices above descri ed simply move away from the bridge 8, With*- 6() out any obstruction, and that in closing lup 7 the pedestal they will merely approach ,it

without'obstruetion, so that the .devices Vdescribed do not interfere in any manner with,

vthe extension of the pedestal. It will also 'lf observed that the dogs, 1l, 1.1a andl, 12?,

having sloping noses on the side opposite their abrupt shoulders which encounter the lips, 9". Since the positioningl spring, 1.4-,

'engaging the scallops, 15, in the edge ot' they..

plate, 9, automatically keeps said plate him one of theltwo positions shown in Figs. 1 and 3 respectively, the table top membersA may be closed together Without regard to the position of the plate, 9, and. 'without reversing the/alternating.reciprocating move# 7%, ment which is necessary in order`to'cont`iol -the extensionpandvthis is the sole purposeI of employing pivotedglogs insteadotl `fixed abutments, which, soltar as controlling the extension is concerned, would be equally ef` 89 fective. A "il v Any ,formof lock may be4 employed for locking the table members togetheigg'jeither in theabseiice ot fillers, or With one or more.' fillers, and the devices above`sho1$ln do not 85 interfere With the employment ot'fsliith ylock ing devices. j .I 1. A

Upon consideration, .it will be 'seen that as thus far described, while the devices shown would tend to insure the alternate extension ofthe oppositetable top membersv one-halfl i filler width at a time, and tend, therefore, I' to prevent the insertion ot' 'one or more leaves otherwise than with their width'equally dis tributed at opposite sidesl ot the original meeting line ot the table-top in'embers,.it would be possible to extend onlyl oneinembei' a haltlill'er width at a' step following each extending` movement by a proper movement' of the-plate, 9, to clear the path of the 100 dog so asv to permit the next step without moving the other top member in the interval or alternately with the first member. vTo render this mode ot manipulation of the device in'ipossilole.v` the dogs and plate, 9, are 105 constructed withotherrfeatures which Will now be described-fV Each 'ofthe dogs, 12 and 12a, is provided with anextension 12", projecting beyond its abrupt shoulder, 12b, a little more than one '110 filler Width, and the lips 9b, have each@J notch, 9, in. which said extension, 12X, is en-A gaged when the table-top members are closed together; This prevents thel movement of the plate, 9, until. both table-top members have been moved away from their meeting position one fillerfvvidth to bring a ',notch, 12%, Which'is iformed in the extension, 12", immediately .infront of the head, 12b, tothe lip; that is, sothatsuch notches 12y oit both 12o dogs 12 register with the "-corres ending notches 9 `ot the plate 9. lThe pate-,can then be moved longitudinally, as already described, ;tor .clearin the 'abrupt head',12b,of

the dog. 'l This renc ers impossible two c'onsee- 125 utive stepmovements of prie tabletop membei; away from the closed position Without an interveningstepmovenient of the other member.y ".ioprevent two successive movements etleitlier member thereafter Without @se an intervening movement of the opposite member, each of the dogs, 11 and 11a, is provided with au extension, 11", projecting forward from the fulcrum of the dog a little more than one-half filler width, so that when the dogs, 12, 12a, are moved by the first step of separation of the table-top members to bring their heads respectively up against the lips, 9b, the ends of said extensions, 11" project'v past theedges' of the lips, 9b, respectively. The lateral edges of these projections, 11","are beveled, as seennlat 112, and the facing edges or corners, 9d, of the lips, 9", are similarly beveled, so that the longitudinal movement of the plate 9, as vpermitted by the registrationv of the notches, 12y and 9", Willcause the lip, 9", at 'each end of the plate, which is advanced inv such movement to collide by itssaid beveled corner with the .beveled edge of. the extension, 11X, causing said extension to rise up over the said beveled corner ofthelip and drop movement in the opposite direction.

into the notch, 9, and locl; the pl-ate against The plate will be released from this engagement and become movable in the OPPOSlte direction after each ofthe dogs .thus engaged has been moved in the direction in which it will be carried by the extension ofthe table-top member to which it pertains a distance equal .'to one-half filler-width; that is, the distance necessary to bring the head 11b of .each dog up to the lip Where the dog is provided with a notch,'11y, through which the lip, 9b, can pass in the reverse movemen'tlof the plate.

With this construction, although it Willbe possible for the operator deliberately to release 'the dogs at the points atvwhich they would normally prevent the secondsuccessive extension movement of either table-top member,that is, without the intervening movement of the oppositev member',-.such successive` movements will not be possible and therefore Will notioccur inadvertently or Without the operator.

Any convenient means may be provided for preventing the latches from dropping deliberate intention of the I too low for action as above described, as-the stop shoulders, 11c and 12, above the fulcrums of theflevers vin position to stop at opposite sides of -the stopA brackets, 13,
